Problems solved by technology

[0003] One of the ways to alleviate the "urban heat island effect" is to increase the water body and water evaporation in the city. However, since the buildings and roads in the city are all brick and cement buildings, when it rains, the rainwater cannot penetrate into the ground and all along the The sewers flowed away; on the contrary, because the capacity of the sewers is limited, the rainwater cannot be discharged when it is larger, resulting in waterlogging on the roads, making it impossible for vehicles and pedestrians to walk, and even flooding into houses, causing property damage

no. 1 example

[0015] The first embodiment: combined with figure 1 to explain. Make a transformation of the green belt, dig the green belt down to a depth of several meters, the depth can reach 3-5 meters, or even more than 10 meters deep, forming a pit (1), and laying bricks around the pit (2) and Smear cement, bottom (3) also smear cement, make pit (1) impermeable; Then backfill the excavated soil, plant flowers and trees (4).

[0016] Its characteristics: when it rains, the rain will be stored in the pit (1), because the surrounding (2) and the bottom (3) are protected by cement, and the water will not flow out of the pit (1). In this way, the accumulated water in the pit (1) can be used to supply the water required by the flowers, plants and trees (4), and the "urban heat island effect" can be alleviated through the evaporation of water.

no. 2 example

[0017] The second embodiment: an improvement on the basis of the first embodiment. combined with figure 2 to explain. Lay a pipe (7) on the ground to flow to the greening pit (1) with the existing downpipe (6) of the house, and when it rains, the rainwater flowing down through the downpipe (6) of the house will flow to the greening pit (1 )Inside.

[0018] Its characteristics: make full use of the rainwater flowing into the green belt pit (1) from the downpipe (6) of the house to supply the water required by the flowers, plants and trees (4), and keep sufficient water in the pit (1); at the same time, it can also It reduces the flow of rainwater from the house to the ground, increases the possibility that the accumulated water on the road is not easy to drain from the sewer, and the accumulated water pours into the house.

no. 3 example

[0019] The third embodiment: an improvement on the basis of the first embodiment. combined with image 3 to explain. Dig a pit (1) deeply with the green belt equally, but the edge (8) of this pit lays stone slabs or bricks, 0.5-1 meter higher than the road surface, and the height of the backfill is flush with the edge (8) of the pit; There are several small holes (9) on the ground at the edge, allowing the road surface (5) to communicate with the pit (1). Additionally, these small holes (9), combined with the attached Figure 4 to illustrate. The aperture on the road surface (5) is larger, 3-5 centimeters, and the aperture in the pit (1) is smaller, 1-2 centimeters; And, the small hole (9) is inclined, and the road surface (5) is higher, and the pit (1) Lower inside. Like this, can prevent the sewage in the rainwater from flowing into the pit (1), can prevent the soil in the pit (1) from flowing out again, flow to the road.

[0020] Its features: because there are severa...

Abstract

The invention discloses a rain collecting project. A green belt in a city is used for planting flowers and plants, and is reformed. The green belt is dug to have the depth of several meters to form a pit (1), bricks are built at the periphery (2) of the pit (1) and cement is applied, and cement is applied to the bottom (3), so that the pit (1) is waterproof; and earth which is dug out is refilled, and flowers and plants (4) are planted. When rain falls, rain is stored in the pit (1), and water cannot flow out of the pit (1) because the periphery (2) and the bottom (3) are protected by the cement. Therefore, water in the pit (1) can be used for supplying water to the flowers and plants, and an urban heat island effect can be lightened due to the evaporation of the water in the pit (1).

Description

technical field [0001] The invention relates to environmental protection technology, in particular to a method for controlling "urban heat island effect". Background technique [0002] "Urban heat island effect", that is to say: the heat generated by human life and production; the building structure and the characteristics of the underlying surface cause more heat to be absorbed; high. [0003] One of the ways to alleviate the "urban heat island effect" is to increase the water body and water evaporation in the city. However, since the buildings and roads in the city are all brick and cement buildings, when it rains, the rainwater cannot penetrate into the ground and all along the The sewers flowed away; on the contrary, due to the limited capacity of the sewers, larger rainwater cannot be discharged, resulting in waterlogging on the roads, making it impossible for vehicles and pedestrians to walk, and even flooding into houses, causing property losses. Such incidents are ...
